Hello, it is best to plant them in the beginning of spring.
How to plant purple yam?
First: seed potato pretreatment, row of seeds
March 15?25 each year, humidity suitable for the storeroom to select a large, strong, unbroken, no insects, no spots of seed potatoes, the surface of the water washed and cleaned naturally dry, and then with the root of the root of the can be used to enjoy the roots of the Banquet Wo agent, the seed potatoes as a whole submerged in below the level of the liquid surface, soaking finished removing the drying of the center of the seed potatoes along the longitudinal section cut into two segments of the tuber, and the seed potato is not a good choice, but it is a good idea. Remove the hay during the day to maintain normal temperatures, and open the mulch every 10 days since the seed potatoes were discharged. Second: purple yam seedling management.
May 5?8, seed potato seedling rate of 96% or more, during the day when the temperature is 15?28 ℃, open the film, if the temperature is higher than 15 ℃ does not need to cover the seedbed film, so that the purple yam seedling can naturally photosynthesize, after 5:00 pm at night or when the temperature is lower than 15 ℃, need to be timely cover the film, to prevent the temperature difference between cold and hot temperature is too large inhibition of seedling growth.
Third: purple yam seedling cuttings cultivation
Each cutting of seedlings by sifting, discard the thin, weak, moth-eaten, yellowed, diseased part of the intact seedlings in the afternoon when the temperature is lower than 20 ℃ planted in the cuttings in the shed, cuttings of seedlings spaced 25cm apart from each other, each seedling next to the insertion of the length of the bracket for the length of 2m to facilitate the growth of yam vine climbing.
Fourth: purple yam field growth management
June 5?8, the growth of seedlings foliar spraying, you can use Ribeiro Banquet Wo large amount of water-soluble fertilizer, after an interval of 5 days and then again sprayed with doxorubicin, before and after a cumulative total of 3 times spraying, June 20 began, every day, after 8.30 a.m., before 4:00 p.m. in the evening, to open the cuttings shed around the ventilation window, to remove cuttings covered with shed Hay or thick film, so that the seedlings can naturally photosynthesize, accelerate growth and development, to the September 10th, completely remove the cuttings shed on the hay or thick film, open the cuttings shed around the ventilation window, so that the purple yam seedlings can be completely free photosynthesis;
(5) Purple Yam Harvesting: in mid- to late-October, the purple yam is ripe and dug up, dry the surface of the purple yam will be placed in the temperature of 10-14 degrees Celsius, humidity suitable for the indoor. 14 ℃, suitable humidity indoor storage.
